Controller Self Diagnosis
Introduction
Operation of the error diagnosis tools added to the main body and remedy for errors are
described. These tools can reduce time to determine cause of errors occurred in field and
improve the accuracy of specifying error locations.
This manual can be applied when the main body is placed in the following conditions.
• An error is suspected to have occurred in the Main Controller PCB 1/2 and other related
PCBs (child PCBs such as SDRAM or TPM mounted in the Main Controller PCB 1/2).
PCBs and units diagnosed by the tool is as follow:
●
Controller System Error Diagnosis Tool
• Main Controller PCB 1 side <Main Controller PCB 1, SDRAM, TPM PCB, FLASH Memory
PCB, PCI Expansion PCB (option)>
• Main Controller PCB 2 side <Main Controller PCB 2, SDRAM, Memory PCB
• HDD (except Flash memory model)

Controller System Error Diagnosis Tool
This tool automatically checks the Main Controller PCB 1/2, child PCBs mounted on the Main
Controller PCB 1/2, and HDD, and display the result on the Control Panel.
This tool is installed in Flash PCB.
Therefore, this tool cannot be used when an error occurred in Flash PCB.
